West Ham United are tracking
The Premiership side have targeted the Welsh international defender as they look to assemble a squad capable of maintaining their place in the top flight next season.
Hammers boss Alan Pardew has already completed the signing of Northern Ireland international Roy Carroll, who was playing at Manchester United until the end of last season.
It is believed that Pardew is keen to add at least four more new faces to his squad having been handed a £20million summer transfer kitty.
Should Ricketts leave the south Wales club, he would command a substantial fee, while still being a bargain for a Premiership club.
Ricketts has just one year left on his contract with Swansea, and has been in talks over a possible new deal which would keep him at the club until 2008.
However, if West Ham up their interest, Ricketts could be persuaded to join countrymen Rob Earnshaw, Mark Delaney, Ryan Giggs, Carl Robinson et al in the Premiership, just a year after playing conference football.
Ricketts is by far Jackett's best signing, and the last year will have been a special one for the 23-year old, who was influential in Swansea's promotion to League One, which lead Wales boss John Toshack to give the former Telford United player his international debut, and cap him a further twice.
West Ham are not known to have contacted the club, and chairman Huw Jenkins remains defiant:
"There's not much to say because nobody from West Ham has made any contact with us about Sam," he said.
"As far as we're concerned we're ploughing ahead this week to get his deal extended.
"He's our player next year anyway."
